My computer is mainly reserved for movies for the TV so would like to avoid installing additional software so I have been using WMP. Im ripping CD's to the music folder with WMP (MP3's).
Ive done some searching and most seem to have issues with album art with MTP. Using WMP12 and MTP and using sync in WMP to sync the files to the J3, the album art shows up in the J3 without issue.

However, with the J3 set to MSC, if I sync within WMP, no album art.
Isnt this the reverse of what most have experienced or have I missed something?

I can grab a jpg of the album cover and save it as cover.jpg inside the album folder (on the PC). But still, going back into WMP and using sync to the J3 , no album art.

Simple drag and drop or copy/paste of the album folder (with cover.jpg inside) to the J3 works fine with J3 in MSC.
Or, I can sync with WMP then perform the additional step of opening up the folder within the J3 and pasting in the cover.jpg album art and the J3 displays it.

But bottom line is that no matter what I do, syncing from WMP with J3 in MSC, no album art.
